Console pops and turns off with no sd card, with sd blue light fades

I have 2 motherboards for my console, one was the original and one was the replacement. I bought the replacement as not working, but I bought it because I plan on taking the good connectors on the new motherboard and putting them on mine. Specifically the daughterboard connector and the touchscreen backlight connector. I was wondering why the new motherboard has the same problem as my old one, especially because the connectors on the new board have no damage. It my be my battery, which is swollen, but I’m not entirely sure.
